Abstract

The present investigation was undertaken to study the effect of genetic and various non-genetic factors affecting the pre-weaning growth traits in Deccani flock of 300 animals maintained at Livestock Research Station, Mahabubnagar, Telangana State from October, 2012 to July, 2015. The least squares means for body weights at birth, 15, 30, 45, 60, 75 and 90 days of age were 2.72 ± 0.03, 4.37 ± 0.07, 5.90 ± 0.10, 7.49 ± 0.12, 9.03 ± 0.14, 10.32 ± 0.15 and 11.48 ± 0.16 kg, respectively.. The analysis of variance revealed significant influence of sex on birth weight (P<0.05); season on 90 days weight at (P<0.01) and parity of ewe on body weights at 30, 45 and 60 days age (P<0.05). The effect of weight of dam was non-significant on all the pre-weaning body weights.
